The last successful build on Cygwin corresponds to rev 8378. Then it fails:
8379 dragos Added InnerClasses attribute in classfiles
8380 dragos Added initial icode reader.
8381 dragos Added initial icode reader.

Splitted "big" match expression in symtab/classfile/ICodeReader.scala as a temporary workaround.

Changed the match statement to allow the patternmatcher to translate it to a simple int switch.
